Hey there!
Oxygen has a molar mass of 16. That means 16g of oxygen is 1 mole.
32.6 ÷ 16 = 2.0375 moles
We have 2.0375 moles.
There are 6.022 x 10²³ atoms in one mole.
2.0375 x 6.022 x 10²³
1.3 x 10²⁴
There are 1.3 x 10²⁴ atoms in 32.6 grams of oxygen.
Hope this helps!
Answer : The value of
for the final reaction is, 184.09
Explanation :
The equilibrium reactions in aqueous solution are :
(1)
![K_{c_1}=4.5\times 10^{-4}](https://tex.z-dn.net/?f=K_%7Bc_1%7D%3D4.5%5Ctimes%2010%5E%7B-4%7D)
(2)
![K_{c_2}=1.1\times 10^{-9}](https://tex.z-dn.net/?f=K_%7Bc_2%7D%3D1.1%5Ctimes%2010%5E%7B-9%7D)
The final equilibrium reaction is :
![K_{c}=?](https://tex.z-dn.net/?f=K_%7Bc%7D%3D%3F)
Now we have to calculate the value of
for the final reaction.
Now equation 1 is multiply by 2 and reverse the equation 2, we get the value of final equilibrium reaction and the expression of final equilibrium constant is:
![K_c=\frac{(K_{c_1})^2}{K_{c_2}}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%28K_%7Bc_1%7D%29%5E2%7D%7BK_%7Bc_2%7D%7D)
Now put all the given values in this expression, we get :
![K_c=\frac{(4.5\times 10^{-4})^2}{1.1\times 10^{-9}}=184.09](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%284.5%5Ctimes%2010%5E%7B-4%7D%29%5E2%7D%7B1.1%5Ctimes%2010%5E%7B-9%7D%7D%3D184.09)
Therefore, the value of
for the final reaction is, 184.09
Answer:
yes
Explanation:
new compounds made, a chemical reaction is when a new compound is made.
increased global populations would probably be a big one
Answer:
